Answer:D can occur in animals through binary fission
Explanation:
Answer:
True
Explanation:
Methanogens are prokaryotic microbes that produce methane as a by-product of metabolism in anoxic or anaerobic conditions. They are commonly found in the gastro-intestinal parts of ruminants, Marine sediments, and wetlands etc. They are responsible for the methane content released when cows burp/belch and the marsh gas of the wetlands.
Methanogens are strictly anaerobic (they thrive best in a no-oxygen condition) and play a vital ecological role by using up excess hydrogen as an energy source and other products of fermentation released during anaerobic respiration. Due to this, methanogens thrive in an environment which has all electron acceptors e.g. Oxygen, Sulphate, Nitrate etc. removed. This excludes CO2 because methanogens use CO2 as their carbon source.
Breast milk composition and frequency of demand feedings separate a carrying species from a nesting species.
<h3>What does patterns of parental care mean?</h3>
The patterns of parental care can be defined as stimuli that shape the relationship between parent and offspring in different species.
Carrying species are those species where parent care do not involve building nests for their offspring (conversely to nesting species).
In conclusion, breast and demand feedings separate a carrying species from a nesting species.

Answer:
The answer is D. Nucleus are only found in Eukaryotes.
The answer is A. Speciation is the process by which new species are formed. It is an evolutionary process where certain biological populations evolve to new distinct species. It was the biologist Orator F. Cook who first coined this term. <span>There are types of speciation </span><span>namely</span><span> sympatric, parapatric, peripatric and allopatric.</span>
